Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

This is for those having trouble with the 'designmodo-flatuipro-rails' gem in a rails app when using Capistrano for deployment.

This gem required that we use the 'less' gem in conjunction with the 'bootstrap-on-rails' gem. This bootstrap gem is the Less version.

The error we are dealing with is this: couldn't find file 'jquery.ui.touch-punch.min'

All of the work will be done in the 'config/deploy.rb' file

after "deploy:bundle_gems", "deploy:flat_ui"
